Low density lipoprotein and very low density lipoprotein are selectively bound by aggregated C-reactive protein
C-reactive protein (CRP), the classical acute-phase protein, can bind phospholipids by virtue of its specific, calcium-dependent reactivity with phosphorylcholine residues. However, analysis of acute-phase serum by gel filtration and by density gradient ultracentrifugation showed that the CRP was in a free, uncomplexed form, despite the coexistent presence of the various classes of serum lipopr...
متن کاملLow Density Lipoproteins Produced in Vitro by Lipoprotein Lipase Action on Nonsuppressive Very Low Density Lipoprdteins*
Very low density lipoproteins (VLDL), Sf60 to 400, from normolipemic individuals do not suppress 3-hydroxy-3-methylglutaryl-CoA reductase activity in cultured normal human fibroblasts at concentrations 20fold higher than those of low density lipoproteins (LDL) that give total suppression. To determine if these VLDL contain all of the structural elements necessary for receptor-mediated suppressi...
متن کاملLipoprotein Lipase Increases Low Density Lipoprotein Retention
Lipoprotein lipase (LPL), the rate-limiting enzyme for hydrolysis of plasma lipoprotein triglycerides, is a normal constituent of the arterial wall. We explored whether LPL affects (a) lipoprotein transport across bovine aortic endothelial cells or (b) lipoprotein binding to subendothelial cell matrix (retention). When bovine milk LPL was added to endothelial cell monolayers before addition of ...

متن کاملVery Low Density Lipoprotein (VLDL)
Triglyceride (TG) or more accurately triacylglycerol is simply a compound of three acyl groups (fatty acids) attached to a glycerol molecule. They are easily measured in the laboratory and reported as serum TG level: it actually refers to all of the TG that are being trafficked within all of the lipoproteins that exist in a deciliter of plasma. A physiologic fasting TG concentration is on avera...
